bar, being a section taken on the line 7-7 of The slide members 24, 24a,in accordance with Figure 5, but in another position of the anchormyinvention, are formed of sheet metal as are ins bar, omitting he d ntpla the guides 19, but the slide members 24, 24a are Figure 8 is adetail of the latch lock and beof box or hollow formation,having theirmargins 55 ing a section taken on the line 88 of Figured; 25 bent aroundthe inturned margins 21* of the guides, to provide grooves receiving theguides; thus affording a telescoping sliding interlocking engagementbetween the slides and the guides. A metal-to-metal engagement isprovided eliminate ing contact of any sharp edges of the metal with thewood frame of the window. It will be under stood that the slides 24, 24afor each sash are of less height'than the guides, and are of the sameheight or vertical length as their respective sash. The sashes arehinged to the slides 24, 24a, so that they may be swung inwardly of theroom as indicated in Figures 2 and 4, and are adapted to have lockingengagement with the slides 26, 26a respectively when swung into theplane of the slides.

The lower sash A is permanently but pivotally secured to its slide 24 bya erally by the numeral 27 which is desirably of the piano-bench type asbest shown in Figure 1. This hinge 27 includes a leaf or leaves 28secured to the face of the slide 24 as by rivets 29 and another leaf orleaves 30 secured to'the sash A, these leaves having the usualvertically aligned and alternated cylindrical hinge lugs 31 throughwhich pass a hinge pin 32 extending substantially the height of thesash. The leaf 30 may be secured to the sash A by screws 33 which at thesame time, as here shown in Figure 3, may secure to the sash a flexiblemetalweather-strip34 also extending throughout the height of thesash andhaving an angular portion 35 which, when the sash is in the plane of theslides, is snugly received in an exterior groove 36 formed in the faceof the slide 24 as by bending a reentrant portiorrofthe metal of theslide inwardly upon itself. The weather-strip 34 is desirably normallyspaced from the sash, in this instance by the hinge leaf 30, so as topermit flexing. of the strip to resiliently accommodate itself to thegroove 36. The sash A is advantageously rabbeted as at 3'7 toprovidethis spacing from the weather-strip 34 and also to accommodate the hinge27. This results also that the sash at 38 laps the angular portion 35 ofthe weather-strip to abut the slide 24'and fur-'- ther safeguard againstentrance of the elements. The slide 26 at the other side of the window,to which the sash A is adapted to' be optionally locked, is generallysimilar to the slide 24 but is formed somewhat like an inverted L havinga reentrant portion 39 in its base forming an exterior groove adapted toreceive a weather-strip on the sash A. For this purpose the sash israbheted as at 40 to receive the base of the L of'the slide, and theflexible metal weather-strip 41, which is also L-shaped as here shown,is secured in this rabbeted portion of the sash as by a screw 42adjacent the upper end of the uprightof the Lof the weather-strip. Onits base, which abuts the base of the slide, the weather-strip isadvantageously bent around upon itself to.forma bead 43 which is snuglyreceived in the groove 39 of the slide. The weather-strip 41 is desir-iably of a flexible metal such as copper, and except where it is fastenedto the sash, is spaced from the sash as at 44 so as to be permitted toflex to'resiliently center andaccommodateitself in the groove in theslide.

I have provided improved means for locking the sash to the slide 26whichas here shown includes the latch-lock indicated as a whole by thenumeral 45 and shown in detail in Figure 8, In this instance, the sashis recessed to receive a latch housing 46 having a face plate 4'? setback into the edge of the sash, asbest shown in Figure 9, and having anaperture 48 therein-to receive hinge indicated gentherethrouglithe latchbolt 49. The latch bolt which may have a somewhat hollow shank 50,together with the casing 46, houses a compression spring 51 whichpresses the latch bolt outwardly through the aperture 48 within thelimits of shoulders 52 which engage the face plate 47.

*hen the sash is swung into the plane of the slide '26 on its hinge 27from its position, as in Figure 4 where it is shown swung inwardly intothe room, the curved or inclined cam portion 53 of the latch bolt rideson the slide 26 and the .latch bolt is retracted until the slide 26 andthe weather-strip 41 are snugly interlocked (at which time the slide 24and weather-strip portion 35 will also be snugly interlocked) whereupon,when the sash is also in vertical alignment with the slide, the latchbolt 49 springs into an aperture 54 in the face of the slide 26;(Figures 5 and 8) this aperture being substantially the same heightvertically of the sash and slide as the latch bolt. Until the: latchbolt is retracted, the sash A is thus securely locked to the slide 26against swinging movement on its hinge?! and also for vertical movementwith the slide 25. For greater security I desirably provide two of thelatch locks 45 adjacent the upper and lower corners of the sash. It willbe understood that when the sash is thus locked to the slide 26, thesash A and the two slides 24, 26 move as a unit upwardly or downwardlyin the channels 8, 8a, and on the guides 19 maintained in these channelsin a state of equilibrium in any selective position therein by the usualsashweights 55 which are connected by cords 56 to the slides as at 57(Figure 5) the guides having openings 58 therein near their tops whichpermit the cords 56 and the usual pulley wheels 59 to turn therethrough.The screw or bolt 57a, securing the cord to the slide, desirably has itshead (not shown) countersunk in the face of the slide, and a nut 5T0 onthe bolt 57a, clamps the parts together, the cord, the inner end of thebolt, and the 'nut being received within the open upper end of the slide26.

I provide simple and novel means for retracting the latch bolts 49 ofthe locks 45 when it is desired to release the sash from the slide 26and swing the sash inwardly. For this purpose I have shown a retractingplate 60 (Figure 9) pivoted as at 61 in the same recess in the edge ofthe sash which receives the face plate 47, to be substantially flushwith the edge of the sash. The retracting plate also has an aperture 62therein which in one position of the retracting plate registers with theaperture 48 in the face plate. By means of a finger-piece 63 on theretracting plate, accessible at the inner face of the window when thesash is in the plane of the slide, the retracting plate 60 may be swungon its pivot trans-.

versely of the sash and latch bolt so that a margin of the aperture 62(beveled as indicated at 62a) rides across the cam surface 53 of thelatch bolt and retracts the bolt from the aperture in the slide, thuspermitting the swinging of the sash away from the slide. To permit thislimited pivotal movement of the retracting plate 60, the plate has anarcuate slot 64 at its end opposite its pivot through which passes thesmall headed stud 65 on the fixed face plate 47.

It will be understood that when the sash is swung inwardly on itsvertical axis, some means must be provided for preventing the slide 26from rushing to the top of the window under the influence of thesash-weight 55. For this purpose I have provided a novel anchoring barindicated generally by the numeral 66, which acts as a weight-restrainerand also, aslater pointed out, serves as a burglar lock. The anchoringbar 68 is pivoted intermedially at 67 upon the interior of the hollowslide 26, as through the intermediation of a bracket 67a. suitablysecured to the interior of the slide, as by the rivets 6717 on the faceof the slide opposite the guide 19. At its lower end the bar has atongue 68 spring-pressed'as by a torsion spring 69 toward the guide 19,adjacent thereto. At its upper end the anchoring bar 66 has an extensionor button 70 thereon which may project through the slide through thehole 71 therein. When the sash is swung away from the slide 26, thespring 69 urges the lower end of the locking bar into one of the slots23 in the guide 19 to lock the slide against vertical movement under theinfluence of the sash-weight, but when the sash is swung into the planeof the slide, the edge of the sash rides over therounded face of thebutton 70 and by abutment with the button 70 rocks the anchoring bar atits lower end out of the slot 23 so, that when the sash and slide arethereafter in the same plane, the anchoring bar is normally ineffective,and the sash and slide, together, are permitted to be raised or loweredand to be.re spcnsive to the counter-balancing influence of j the weight55. There are times, however, when lock. To accomplish this result thebutton '70 on the anchoring bar normally abuts a manuallymovable detentplate 72, pivoted at 73 on the edge of the sash adjacent the button 70.The detent plate 72 has. a-finger-piece 74 accessible at i the innerface of the window so. that the detent plate may be swung out ofabutment with the button 70. The edge of the sash is recessed behind thedetent plate at 75, as'best shown in Figure 7, to permit the button 70to spring into this recess and the bar to rock so that tongue 68 thereofmay be received in one of the slots 28 in the guide even when the sashis in the plane of the slides. As best shown in Figure 9, the detentplate 72 is conveniently carried by face plate '76 which is discontinuedopposite the recess 75, and the face plate 76 and detent plate 72 areset into the edge of the sash to be substantially flush therewith, justas are the face plates 47 and retracting plate 60 of the latch looks.The anchoring bar and its operating mechanism are desirably locatedmedially of the sash and slide and are thus identified by the user,while the latch locks 45 are located nearer the corners of the sash.

The upper sash B and its slides and guides are similar to sash A, butsash B is somewhat narrower than sash A.(the channels 9, 9a being closertogether than the channels 8, 8a as already mentioned) to permit sash Bto be swung on itsvertical axis past the parting strips 13 and the slide26. It will be understood also that, for adaptation to old windows,where the channels 8, 8a and 9, 9a. are equal distances apart, theslides for the sash B may be made wider (as 24b, in

Figure 10) to accommodate the smaller width for the sash B.

A common objection to windows of this type is that the sash B isprevented by sash A from swinging inwardly to a convenient angle, and Ihave provided novel means for permitting the sash B to swing to asufficiently useful angle and more nearly parallel with the sash A whenthe sashes are in extreme inwardly-swung position. For this purpose Ihave provided a double-acting hinge for the sash B, indicated generallyby the numeral 77. This hinge may include the usual leaf or leaves 78suitably secured to the face of the slide 24a, an intermediate leaf orleaves 79 pivoted to the leaf 78 by the hinge pin 80, and another leafor leaves 81 suitably secured to the sash B and pivoted to theintermediate leaf 79 by the hinge pin 82, the intermediate leaf 79 thusspacing the sash from the slide 24a when in its swung position as shownin Figure 4 and permitting the sash to pass somewhat around the sash A.When the sash B is swung to closed position into the plane of the slides24a, and 26a, the leaves 78, 79 and 81 fold together as shown in Figure3 into a relatively small space, the sash B being rabbeted similarly tosash A for this and other purposes.

The sash B is provided with similar weatherstrip provisions as sash Aand with similar latch locks and anchoring bar, all of which need not beagain described.

It will be understood that when the sashes are swung to closed positioninto the planes of the pairs of slides respectively, the sashes andtheir respective slides 26 and 26a may not at first register vertically.It is desirable, however, that the sash shall always be vertically inregister or somewhatabove its respective slide 26 or 2611, as the casemay be, when-first swung into the plane of the slide, and for thispurpose I have provided a shelf 83 on the foot of the slide 26 and asimilar shelf on the foot of the slide 26a so that its respective sashcannot be swung into its plane unless the sash is above this shelf.Thereafter, the sash may simply be pushed down until it rests on theshelf 83, or, as generally happens, the weight 55 will pull the slide upto locking position in register with the sash. The sash is desirablyrabbeted to receive the shelf flush with the lower edge of the sash.When so received, the latch locks 45 are operative automatically,provided the retracting plates 60 are centered to have their apertures62 in register with the apertures 48 and 54 so that the locking boltsare projected through all of these apertures. is in register with thebutton 70 to permit the anchoring bar 66 to be operative as a burglarlook when the detentplate '72 is swung to expose the recess 75. At thistime if the sash A is in its lowermost position and the anchoring baroperative, the tongue 68 will be received in the lowermost slot 23 ofthe fixed guide 19 and the sashwill be locked in this lowermostposition.

It will be further understood that when the sash is in its lowermostposition, for weatherexcluding purposes, it. is desirably depressedbelow the ledge 84 of the window-frame 10, as shown in Figure 2. When itis desired to swing the sash inwardly, as already described, the sashand its slide 26 must of course be raised slightly above this ledge 84.Similarly, with the upper sash B as shown in Figure 2, it must belowered at least slightly from its uppermost position before it can beswung inwardly, and usually the upper sash B islowered into the samevertical plane as the At the same time also the recess 75 sash A beforeit is swung-inwardly, as this places both of the sashes at a convenientheight for cleaning the outer face thereof.

If desired, a filler 87 such as ablock of wood or the like may be shapedto the cross-section of the slides 26 and 26a and-secured in the foot ofthe slide, as indicated in Figure 5, to stop drafts from passing throughthe slide.

Any suitable meansv may be provided for weather-excluding purposesbetween the sashes A and B, and in this instance I haveshown'the sashesprovided with check-rails 88 and 89 respectively, which when the sashesarein fully closed position; meet tightly on a plane 85 (Figure 2) whichis somewhat inclined to cause a wedging action between the sashes, thatserves to exclude weather at this point. It will be noted that myimproved double-acting hinge 7'? permits the sashes to be constructedwith these meeting check-rails, as without the double-acting hinge forthe upper sash B thecheck rail'89 could not be swung past the partitionstrip 13. The usual catch 100 may be employed to lock the sashestogether.

' While the construction I have shown and described ishighly-weather-proof and at the same time substantially noiseless inoperation, I may make further provision for maintaining a tightwater-proofand non-rattling, engagement between theparts as by resilientmeans such as the leaf springs 86 carried on the inner faces of theslides at one or more points thereon and pressing against the guides 19to press the parts yieldingly but firmly together and at the same timeto permit free sliding movement of the slides on the guides.

In this instance the bowed portions of the springs 86 ride on the offsetcenters 22 of the guides. Also the springs 86 will provide enoughfriction to permit the sash-weights 55 to be eliminated, if desired, forvery small windows.

Obviously, the invention is not limited to the details of constructionshown for purposesof illustration. Furthermore, it is not essential thatall features of the invention be used conjointly, as variouscombinations and sub-combinations -may be variously and advantageouslyemployed.
